The present invention relates to a flow control device of an intercepting sewer with an integrated inspection hole. According to the present invention, the inspection hole, which inspects inside of an overflow chamber, is integrated into a frame to easily inspect or dredge inside of the overflow chamber without detaching the frame. In addition, a water-barrier plate is connected to both sides of the opening /closing plate and of a stopper plate to prevent fine impurities from entering to the flow control device. Therefore, an operation failure of the opening/closing plate is prevented. |
